Dine-Navajo Pot by Susie Charlie; What is Name of This Shape?

This is 7 1/2" major diameter, 3 1/2" rim diameter, 3 3/4" high, the bottom is flat out to about 5" diameter; weight is ~2 lb.
I was first attracted to it for the odd number of stairway peaks; 11 above, an 17 beneath...odd divisions of a circle is one of my peculiar fetishes. The stain in pics 2,3,4,5 & 6 were on it when I acquired the pot, for very little money, in Bishop, California in the mid 1990's. I don't think I've shown it here previously.
NA pottery, especially Navajo, often have functionally-named shapes (wedding vase, seed pot, etc.), but I cannot find one that matches this pot. Your help will be most gratefully welcomed...Thanks for lookin'!

 

Here's another thread about something similar. Pay particular attention to Taupou's comments (always!!).
